I don't know why anyone would make mean comments about your mom wanting to adopt Queen, and if they did, it would be just plain rotten.
That is wonderful that you are thinking of adopting her. She is a very pretty dog, and sounds like she would be a delightful companion. I'm sure she will be very grateful if you guys decide to adopt her. And as many people demand cute little puppies, you are doing a wonderful thing by giving her a great home. Hope all goes well for you.
